Exactly. As another user in this thread pointed out, people tend to apply microeconomic thinking to macroeconomic problems. They think in monetary terms, but money is irrelevant in this context. What matters is produce, the capital to produce, and the power to enjoy produce (which money represents, currently).

There is no way to "save" money for the retirement, without also making sure the economy fares well as you age. If your country's economy does not produce anything at the point of retirement (and no other country is sending you their products, either forced, because your society projects military power, or freely, because their society thinks it's inhuman for your population to suffer), your saved currency is worthless.
